Hi

Could you tell me which firefox for windows 7 browsers are supported by Mozilla. e.g. currently it is 48.0.2 but for example is 1.08 and 2.0.0.20 supported currently. Is there a matrix showing browsers supported and not supported.

Chosen solution

yes, the first part is correct.

the current base release for esr is firefox 45 - as tomorrow is release day, the new incremental esr version will be 45.4.0 and it will continue to be supported until 45.8.0 mid next year. the next base for the esr version will be firefox 52, which will run in parallel with esr 45 for two cycles (45.7.0 & 45.8.0) as shown in the chart from my prior link. as all the other releases of firefox, esr is open source and totally free of charge!

hi 195bets, only the latest version of that release matrix is supported by mozilla at a time. then there are also the pre-release versions beta, developer edition & nightly which receive security updates and finally the "extended support release" ESR version of firefox intended for organizations: https://www.mozilla.org/en-US/firefox/organizations/faq/

Hi

Thank you for the reply. Can i just clarify so i understand .

Firefox for windows will be support the current release, which currently is version 48 and all sub patches e.g. 48.0.1 and 48.0.2. This will remain in support till version 49 is released.

For ESR you get 12 months support which is nine release, so if it is currenlty v48 nine releases will be v57.

Is the above correct? Also do you have a link for how much this extend support costs?

Regards

thanks again., that now makes sesnse. The first instance is for single users. ESR is for large organisation that need stability in version which ESR gives for a 12 month period where it will then come to a version which is in line with single user.

One final question. Is there any formal support for mozilla firefox for large organisations?
